## org.junit.rules
Class ErrorCollector

    java.lang.Object
      org.junit.rules.Verifier
          org.junit.rules.ErrorCollector

All Implemented Interfaces:
  MethodRule

    public class ErrorCollector

extends Verifier

The ErrorCollector rule allows execution of a test to continue after the first problem is found (for example, to collect _all_ the incorrect rows in a table, and report them all at once):

     public static class UsesErrorCollectorTwice {
            @Rule
            public ErrorCollector collector= new ErrorCollector();

            @Test
            public void example() {
                    collector.addError(new Throwable("first thing went wrong"));
                    collector.addError(new Throwable("second thing went wrong"));
                    collector.checkThat(getResult(), not(containsString("ERROR!")));
                    // all lines will run, and then a combined failure logged at the end.
            }
     }

Constructor Detail

### ErrorCollector

    public ErrorCollector()

Method Detail

### verify

    protected void verify()
                   throws Throwable

  Description copied from class: `Verifier`
  Override this to add verification logic. Overrides should throw an exception to indicate that verification failed.

  Overrides:
    `verify` in class `Verifier`
  Throws:
    `Throwable`

### addError

    public void addError(Throwable error)

  Adds a Throwable to the table. Execution continues, but the test will fail at the end.

### checkThat

    public <T> void checkThat(T value,
                              Matcher<T> matcher)

  Adds a failure to the table if `matcher` does not match `value`. Execution continues, but the test will fail at the end if the match fails.

### checkSucceeds

    public Object checkSucceeds(Callable<Object> callable)

  Adds to the table the exception, if any, thrown from `callable`. Execution continues, but the test will fail at the end if `callable` threw an exception.
